7.3.4 Product Certification Classifications
Product certification is classified into compulsory certification and non-compulsory
certification.
Compulsory certification
Many countries and regions define compulsory certification marks to facilitate
market supervision of the commodity inspection organizations. For example, the
Certification Europe (CE) mark, Federal Communications Commission (FCC)
mark in U.S.A, and China Compulsory Certificate (CCC) mark are compulsory
certification marks. Only the products with required compulsory certification
marks can be sold in the relevant countries or regions.
Non-compulsory certification
Non-compulsory certification is also called voluntary certification. Compared with
compulsory certification marks, the certification marks issued by independent
certification bodies are more common in international trade. The PCS Type
Certification Review Board (PTCRB) in America and the Global Certification
Forum (GCF) in Europe are two typical examples of non-compulsory certification
marks. Non-compulsory certification marks are issued by authorized non-
governmental certification bodies based on the product liability laws in relevant
countries and are recognized by the local governments. Compared with
governmental bodies, non-governmental certification bodies are more
professional with better test conditions and more positive certification measures.
In addition, non-governmental certification bodies are under supervision of their
authorizing administrations. For these reasons, the certification marks issued by
non-governmental certification bodies are widely recognized in the market and
are essential to international trade.
7.3.5 Certification Modes
DOC
By affixing a certification mark to a product, the manufacturer declares that the
product is compliant with the relevant certification standards. For example, a
manufacturer declares that its product complies with relevant EU directives if it
affixes a CE mark to the product.
NB certification
By affixing a certification mark issued by an authorized certification body to a
product, the manufacturer declares that the product passes the NB certification
tests and complies with the relevant certification standards. The CE0682 mark
issued by CETECOM, the UL mark issued by UL, and the GS mark issued by
TUV Rheinland are three examples of NB certification marks.
NB certification is used for Huawei modules in most cases.
